Question

In a one electron system, the probability of finding the electron within a shell of thickness or at a radius of r from the nucleus is given by the radial distribution function P() PR). An electron in a 1s hydrogen orbital has the radial wavefunction R(r) given by: R(r)-21 ne rn, where ao is the Bohr radius (52.9 pm) Calculate the probability of finding the electron in a sphere of radius 2.4ao centered at the nucleus. Number 95
